Features of modern batteries

Contrary to popular myths on the Internet, modern Li-ion batteries do not need to be constantly completely discharged. They do not suffer from the "memory effect" that reduces the actual capacity, unlike older NiCd batteries.

The only problem that regular Li-ion partial charging can cause is when the gadget incorrectly estimates the remaining battery life. The problem can be solved by discharging the device once to 100% in the off state. It is not necessary to leave the device dead for a long time - for a Li-ion battery, being in a completely discharged state for a long time leads to battery damage or to a partial loss of capacity.

Most manufacturers describe battery life in cycles of full discharge to 0%. This indicator for modern batteries is approximately 500 - 1000 cycles. If the gadget is put on charge at a value of 10 - 20%, then this will not mean complete discharge, and the cycle time will approximately triple.

Visual inspection of the battery

You do not need to be an expert to distinguish a damaged battery from a “healthy” one. Most of the problems can be seen with the naked eye. If the tablet or smartphone has a removable battery, then it should be removed after turning off the device first. After this, the following symptoms should be checked: swelling, white or greenish spots, corrosion around the metal contacts.

If this is observed, then soon the gadget may generally become unusable. If you find a battery shape distortion or suspicious spots, you should immediately purchase a new battery. A problematic battery cannot be put back so that the electrolyte does not spill into the device and damage it.

"Rotation Test"

Lithium-based batteries degrade with every cycle. Improper storage only exacerbates the situation - for example, hypothermia or overheating significantly reduces battery life. If one excellent way to break a battery is to discharge it to zero and stay in that state for a long time.

The battery can gradually swell, and the process occurs over weeks or months. Immediately and not notice a slight bend. A simple test will allow you to check this: the battery to be removed should be placed on a flat surface and twisted. If it rotates easily, then this is not a good sign.

Not all batteries can be easily and quickly removed and examined. In this situation, you need to pay close attention to the speed of battery discharge. Should alert the loss of two or more percent immediately and a quick discharge to 0 in a couple of hours. These signs indicate that the battery will soon become unusable.

Software ways to check the battery on Android

Android encrypted in the system contains a log of battery information. This information can be obtained using special utilities. For example, the Battery application, "Battery Care" and other analogues.

Increase

You can find various magic codes on the Internet, but they do not work in new versions of Android. In addition to the number of charge and discharge cycles, these utilities show the operating temperature of the battery. You should pay attention to this parameter if the battery is very hot.

AccuBattery for Android

The AccuBattery application reads information from the battery controller and displays it in a visual shell. The utility helps you choose the most optimal charge, determine the applications that consume the gadget's charge the most and learn about the current battery wear.

Development of AccuBattery began after attempts by Dutch engineers to extend battery life. This is not about slowing down the discharge during the day. The goal is to ensure that battery capacity is not lost after many months of use. The problem is also relevant because many modern gadgets come with non-removable batteries.

The developers conducted a series of tests, as a result of which important conclusions were drawn. It is not necessary to charge the device throughout the night, as the power source loses its capacity during reboots. The reason for this is the chemical processes that take place in the battery.

Mobile devices have an internal switch that stops charging when it reaches 100% and continues to ooze power, which affects the oxidation resistance of certain chemicals. It turns out that for a full charge, the tablet or phone must be disconnected from the mains as soon as possible, after one hundred percent charge.

The most optimal battery charging option is 80%. The AccuBattery app has a built-in alarm that gives active alerts when the battery reaches its optimum level. It is located in the "Charging" menu.

Section "Charging"

At the top of the working window there is a roundness, in the green part of which the current percentage of charge is shown, and in the blue part - acceptable. The threshold of 80% is set by default, but you can decrease or increase it. To do this, you need to move the slider and pay attention to how this affects the damage to the battery.

Increase

If you scroll down the window even lower, you can find out the charging speed of your device from various power sources. For example, connect the "native" charging, then turn off the device for a couple of minutes and look at the Charge speed tab. It indicates the exact information about the amount of time left until the optimal charge. To compare the speed, you can repeat the steps with an external battery or other charger.

Section "Discharging"

This section displays statistics on battery consumption since the last charge. The following information is available in the Battery usage subsection:

• How much interest is spent when the screen is off or on and for what period of time.
• Which application consumed the most ampere-hours (mAh).
• How long the gadget is in sleep mode, how often this mode was interrupted.

Increase Increase

You can also consider a list of applications that actively used the battery. The developers of AccuBattery claim that their way of changing is more accurate than that offered by the Android system.

Sections "History" and "Health"

The "Health" section is the main advantage of the application. When connected to a power source, it starts tracking exactly how much energy enters the battery and what percentage of a full charge it is. Based on the information received, the residual capacity is determined. To obtain a more accurate determination of the current capacity, several long charging cycles should be carried out.

If you compare the nominal with the residual capacity of the battery, you can find out how much it has decreased during operation. Two charts are also available to the user:

• wear for each day of use.
• The level of real capacity, measured as a percentage of the factory.

Increase Increase

The History section contains information about each discharge and charge. If there is not enough general data, then you need to click on any of the presented cycles.

Batteries are perhaps the weakest link in modern gadgets. If earlier it was enough to charge a push-button phone 1-2 times a week, now smartphones (even with the most capacious batteries) have to be connected to the outlet almost every day.

It is clear that such an intensive mode of operation leads to a rapid "burnout" of the battery life. And often the user has to limit himself in communication so that the phone can "hold out" until the end of the day.

Norms and realities

According to the manufacturer, the average life of iPhone lithium-ion batteries is about one and a half to two years. In practice, this is how it is, with some adjustment for the intensity of use by different owners.

Over time, the battery capacity begins to inevitably degrade, no matter how gentle the mode of operation and charging you observe. A few months after the start of active operation, the capacity decreases by 10%.

The average number of “charge-discharge” of a smartphone battery is about 500 cycles (i.e. full discharge after 100% charging). After passing them, the battery capacity degrades by 30 percent. At the end of the next five hundred cycles, the capacity will decrease by half.

All this negatively affects the battery life of the smartphone. It has to be recharged more and more often, as it keeps its charge worse. Many users want to find out how worn out the battery of their gadget is in order to know about the approximate timing of its replacement. Especially when it starts to turn off spontaneously or the device reboots for no reason. Also, this information is very important when buying used devices.

In principle, information about the deterioration of the battery can be provided to you at the service center after the diagnosis. However, for this you will have to spend time going to the center, and a lot of money for maintenance.

If you want to independently determine how many approximately charging cycles are left for a smartphone battery, keep in mind that you cannot find out this information only by using regular iPhone services. You have to use third party apps. Thankfully, there are plenty of tools to choose from today.

Services to find out the number of completed cycles

So, how do you know how many recharge cycles your iPhone battery has left? Depending on whether you have a jailbreak or not, you can choose the appropriate resource. It is clear that there are a lot of them, we will give only a few of them - those that do not require any intervention in the regular operation of the smartphone system.

The popular Chinese "iTunes-analogue" - iTools will help in this matter. It is cross-platform (that is, there are adapted versions for both Windows and Mac) and is distributed free of charge. Please note that on computers running Windows, before using this utility, be sure to install the latest version of iTunes. You do not need to run it - it just needs to be on the computer. Otherwise, iTools will not be able to work, as it partially uses its resources.

After installing and launching the application, connect the iPhone to the PC. In the device details tab, among other data, the number of completed charge cycles will be indicated. And you, starting from the standard value equal to 500 cycles, will be able to navigate by the degree of deterioration of the resource of the battery module.

The above example shows that, most likely, the owner will have to replace the battery in the near future. This device has already completed 426 full charge cycles. But, however, this does not mean that after the mentioned number of recharges, the battery will definitely fail. It will simply become less productive, and the user will have to look for a recharging outlet more often.
If you plan to continue using this application for other purposes (for example, for its intended purpose - to create and manage "backups"), we recommend that you temporarily disable iTunes updates. To avoid version conflicts when installing iTools updates that come out less often.

There are also problems with the Russification of the "native" version of the software in Chinese - be prepared for delays when updates are released. Although the menu is intuitive, and, if necessary, you can be guided by universal icons.

You can also view information about the remaining number of cycles through the iBackupBot application, also originally designed for creating backups. When using it, you do not need to do any jailbreaks, etc. abuse of the Apple ecosystem. However, it also requires that you first install the current version of iTunes.

In principle, this application is paid - about $ 20 in the minimum "configuration". But there is a free trial download option.

To obtain the data we are interested in, you need to download the application to your computer, connect an iPhone to it, and view the battery parameters in the device information section.

In this case, the iPhone went through 273 full charge cycles, so the user does not need to change it yet.
Well, of course, this utility will also allow you to create and manage backups from all your Apple devices.

Another interesting service is an application with the eloquent name "BatteryLife". It also does not require any intervention in the operation of the iOS system, and is installed directly on the smartphone. Once launched, the utility quickly evaluates the basic parameters of the battery, displaying data on its capacity, the number of cycles passed, temperature, discharge level, etc. statistical information.
Plus, this application will indicate how worn out (in percentage terms) your iPhone battery is. And along the way, it will give an assessment of whether it is good, bad or excellent, because. for many, the data on the number of cycles passed, in fact, does not say anything.

And this provides comprehensive information that is understandable for a user of any level of "advancement" - very convenient and fast! It is noteworthy that it can be viewed directly on the smartphone screen, without the use of third-party devices.
No less informative is the free app. — CoconutBattery. Initially developed for macbooks, over time, this utility got the opportunity to also evaluate the parameters of iPhone batteries. The application launches successfully and works correctly both on the smartphone itself and via Mac - choose how it is more convenient for you to receive information.
In addition to the current information about the battery, here you can see all the data about your smartphone in the "Device details" tab, up to the age of the device (which is extremely important when buying a used iPhone). It is also possible to request a statistical history for any date selected by the user - indicating the number of cycles, the change in capacity during operation and the total percentage of wear.

Here's how it looks on the screen of a smartphone and Mac, respectively:
Thanks to this, the dynamics of degradation of the battery life is effectively monitored. And it is possible to take timely measures to slow down this irreversible process. What needs to be done for this?

Extend battery life!

Finally, here are some tips for extending battery life. First of all, follow the recommendedApple temperature regime, since both frost and heat adversely affect battery capacity. Its wear is accelerated by 10-15%. Therefore, we do not leave the iPhone under the open sun, in the cold - we keep it in our pocket.

Try not to bring the gadget to either full discharge or full charge. It is optimal to maintain a constant energy level in the range of 30-80%, gradually recharging during the day. For the same reasons, you should not leave your smartphone on charge all night (except when updates are being performed or backups are being created). Thus, you will significantly extend the period of one complete charge cycle.

We also recommend updating the firmware regularly, as it often improves the performance of the device due to software optimization, while reducing energy consumption. And use only branded chargers for recharging. Non-certified fakes will kill the battery faster due to jumping currents and voltages.

All Apple smartphones and tablets are equipped with a Li-ion battery, which allows the iPhone and iPad to work without the need to be constantly connected to a power source. Unfortunately, all lithium-ion batteries have their own life cycle, which is measured by the number of charge cycles.

The battery of any generation of iPhone and iPad is rated for approximately 500 charge cycles. This means that the device should be discharged by 50,000% in total. It is worth noting that one charge cycle is equal to 100%. For example, if you discharge your iPhone or iPad to 25% in one day, put it on charge at night, and start using it again in the morning, then one cycle will end when it reaches 75%.

If you calculate, then 500 iPhone and iPad charging cycles is about 1.5-2 years of daily use of the device. After this period, the battery loses approximately 20% of its capacity, and also becomes more vulnerable to temperature extremes, due to which the iPhone even with 25% of the remaining charge.

Upon reaching the 1000 cycle mark, the battery capacity of an iPhone or iPad will drop to 50%. On average, this indicator can be achieved in 3-4 years of using the device. This period is best for visiting a service center, because with half the capacity, the iPhone will hardly be able to work for 2-3 hours with the screen on.

If the device was purchased on the secondary market, then it is rather problematic to find out the condition of the iPhone or iPad battery. It is for such cases that the definition of "Cycle" exists. You can find out the number of charge cycles using the program battery life, available in the app store .

In the Battery Life program menu, select Raw Data, then look at the Cycles value, which displays the number of battery charge cycles.

You can also find out this data using a computer based on Windows or Mac OS X. To do this, you will need to download and install the iBackupbot program. After launching the program, you need to connect your iPhone or iPad to your computer, and then select the connected device in the Devices section.

On the page that appears, you will need to click on More Information, which contains the CycleCount indicator. It displays the number of battery charge cycles.

Until December 22, inclusive, everyone has the opportunity to Xiaomi Mi Band 4, spending only 1 minute of their personal time on it.

At a certain stage of using the iPhone, the user wonders if it is necessary to change the battery on the smartphone? And how to understand when you still need to change the battery on the iPhone? One measure of the life of an iPhone battery is the number of charge cycles.

The battery charge cycle is the rate at which your smartphone was charged and then discharged. Therefore, one cycle should be understood as 1 charge and 1 discharge of the battery.

With prolonged use of a smartphone, the battery gradually loses its ability to accumulate energy and becomes unusable. As a rule, this becomes noticeable in the battery life of the smartphone. Typically, iPhone battery life is 500 charge cycles. After overcoming the threshold of 500 cycles, the battery holds its charge worse and you need to think about changing either the battery or.

How to find out the number of iPhone charge cycles?

There are no standard verification methods, but a jailbreak is not needed either. The iBackupbot program will help you find out how many charge cycles have already been. You can install it on MacOS and Windows. You can download the program at www.icopybot.com.

Important: iTunes must be installed on the computer. Without it, the program will not work.

After the program installation procedure, we connect the iPhone to the computer and launch iBackupbot. A window with information about your iPhone will immediately open in front of you.

Go to the "More Information" section ( More information) A new window will open with detailed information. The first line in the "Battery" section is the "CycleCount" parameter - this is the number of charge cycles of your iPhone.

Key metrics from the battery section in iBackupbot

• CycleCount- number of cycles ( battery charging/discharging);
• DesignCapacity- battery capacity in mAh ( original battery capacity declared by the manufacturer);
• FullChargeCapacity- volume of full charge ( indicator that shows how much battery is fully charged today);
• Status- status ( i.e. battery status working / not working);
• BatteryCurrentCapacity- current battery level.

From the example, you can see that the iPhone 5 battery has 708 charge cycles. Moreover, the volume of a full charge is less than 40% (500 mAh) of the declared volume (1430 mAh). If you have a figure of 70-60%, this also indicates that the battery on your iPhone needs to be changed.

When buying a used iPhone, future owners pay attention primarily to the appearance of the smartphone.

I would like to take a closer look at the case: examine it for scratches and chips, take a closer look at whether all the details of the case are tightly assembled, whether the lid or even the screen is loose, etc.

More demanding customers check the quality of the connection (the speaker and microphone), and some want to check the battery of their future iPhone. So, it is at this point that we will stop.

How to find out the number of battery charge cycles on an iPhone using a PC

In addition to this question, we will help you find out the level of battery wear on the iPhone

To determine the number of battery charge cycles, a useful application called iBackupbot comes in handy. You just need to download from the proposed page and install on your PC. Then we do everything as in the screenshots below.

After starting the program and connecting the iPhone to the PC, we see such a window. We click on our smartphone, and then in the right part of the window we look for the button “More Information” and click on it.

Immediately after that, a new window of this type will appear:

The first item in the open window is named "Battery". The first sub-item is called "CycleCount". Its numerical value, in our case 355, represents the number of charge cycles for our iPhone's battery.

How to Check the Number of Battery Cycles on an iPhone Using the Mobile App

The second method involves the use of a special mobile application called "Battery Life". You can download it for free from the App Store by simply entering the name in the search.

So, the program is installed. We launch it and see the main screen. On the main screen we see the inscription “Wear Level”, the state is “Good”. This is a general measure of the health or battery life of an Apple mobile device.

There are four possible options:

1. Perfect (excellent)
2. Good (good)
3. Bad (bad)
4. Very Bad (very bad)

We look for the fourth item "History" and tap on it with our finger. A new window will open in which we are interested in the sub-item "Cycles". This numerical value means the number of iPhone battery charge cycles.

That's all. It will be interesting to know your options for solving this problem in the comments.
